Why, is that a MONTANA 60 you're drinking?

Here is the recipe for a very refreshing cocktail I concocted out in the wilderness of Fortine, Montana. It's a makeshift take on an old classic, the French 75. I'm on my second one right now and feel so lovely that I just had to share it with ya'll.

Fill a highball glass with ice.
Pour a "five count" of vodka (my new favorite way to measure alcohol without a jigger, courtesy of my sister-in-law).
Fill glass with grapefruit juice to about two-thirds from the top.
Squeeze in a slice of lime.
Top with champagne and stir once, gently.

The "60" is in honor of my mother-in-law's birthday, the reason for our trek to the wild wild west. Jury's still out on whether or not this posting will be the extent of my revelations regarding the trip. I mean, what more could I possibly have to say about traveling with the entirety of my in-laws?
